ABR—好氧工艺处理生活污水的试验研究

采用自行设计的ABR-好氧工艺处理营区生活污水,考察了其对污染物的去除效果和抗冲击能力.试验结果表明,该工艺在水质、水量发生变化的情况下,系统运行稳定有效,具有较强的抗冲击能力.当HRT≥7.38h,进水的COD、BOD5分别为149～410 mg/L和114～206 mg/L的情况下,对COD和BOD5的去除率分别可达83%和86%,出水浓度分别为45～52 mg/L和21～25 mg/L,均优于<污水综合排放标准>(GB 8978-1996)的一级标准.系统对SS、TP也有很好的去除效果,SS的出水浓度保持在5.35～13 mg/L,对TP的去除率也在48%左右.基于经济合理性的考虑,认为HRT=7.38h为ABR反应器处理营区污水的最佳水力停留时间.

Experimental Study on ABR/Aerobic Process for Treatment of Domestic Sewage

A self-designed ABR/aerobic process was used to treat domestic sewage from barracks area,and the removal efficiency of pollutants and the ability to withstand shock loading were investigated.The results show that when the sewage quality and quantity change,the system can be operated stably and effectively with strong ability to withstand shock loading.The removal rates of COD and BOD5 are 83% and 86% when the influent COD and BOD5 range from 149 to 410 mg/L and 114 to 206 mg/L and the HRT is equal to or mor...
